Hi, I am trying to solder aluminum with a propane torch. I am unable to do it. I am using .063" 6061 aluminum. I have tried silver solder, Al-3, and Muggyweld Super Alloy 5. I have only gotten Al-3 to work one time. The others don't work at all. I am using a propane torch, I don't have an oxy/acetylene set up. I have the Bernzomatic TS 3000 torch tip on a propane tank. The people at Muggyweld told me that this should work. It doesn't. They make it look easy, See the video here.

I have taken seven welding classes at the local community college so it's not like I am a total amateur at this. But I still can't do it.
Thanks for any help that you can give me.
